A certain gas has a volume of 500.0 ml at 77.0c and 600.0 torr. calculate the temperature if the volume decreased to 400.0 ml and the pressure is increased to 760. torr and assume the number of moles does not change.
As the volume is decreased and the pressure is increased to the given value, the temperature of the gas increases to 81.67°C.
Given the data in the question;
Initial volume of gas; [tex]V_1 = 500.0ml = 0.5L[/tex]Initial pressure; [tex]P_1 = 600.0torr = 0.789474atm[/tex]Initial temperature; [tex]T_1 = 77.0^oC = 350.15K[/tex]Final Volume; [tex]V_2 = 400.0ml = 0.4L[/tex]Final pressure; [tex]P_2 = 760torr = 1.0atm[/tex]Final temperature; [tex]T_2 =\ ?[/tex]Combined gas lawCombined gas law brings together both Boyle's Law, Charles's Law, and Gay-Lussac's Law. It states that "the ratio of the product of volume and pressure and the absolute temperature of a gas is equal to a constant.
It is expressed as;
[tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}[/tex]
We substitute our given values into the expression above to determine the new temperature.
[tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}\\\\P_1V_1T_2 = P_2V_2T_1\\\\T_2 = \frac{P_2V_2T_1}{P_1V_1}\\T_2 = \frac{1.0atm\ *\ 0.4L\ *\ 350.15K}{0.789474atm\ *\ 0.5L} \\\\T_2 = \frac{140.06LatmK}{0.394737Latm}\\ \\T_2 = 354.82K\\\\T_2 = 81.67^oC[/tex]
Therefore, as the volume is decreased and the pressure is increased to the given value, the temperature of the gas increases to 81.67°C.

If 86.4dm^3 of carbon dioxide gas contains N × 10^23 molecules at room temperature and pressure, find the value of N.
At T 25 ° C (298 K) and P 1 atm are stated by RTP ⇒ Vm = 24.4 liters / mol
86.4 dm³ = 86.4 L = 86.4/24.4 = 3.54 mol
1 mole = 6.02.10²³ molecules

Each of the colored lines in hydrogen's emission spectrum corresponds with the C. transition of an electron from a higher energy level to a lower energy level.
What is an emission spectrum?An emission spectrum can be defined as the range of wavelengths, frequencies or pattern of bright lines which can be seen when the electromagnetic radiation that are emitted by an atom of a chemical compound (substance) moves through a spectrometer.
Generally, this process leads to the quantization or transfer of an electron from one energy level to another such as the transition of an electron from a energy level of higher magnitude to a lower energy level in hydrogen's emission spectrum.

how many grams of hno3 would you need to prepare 5.5 l of this solution
8305 grams of HNO3 would be needed to prepare 5.5L of a solution. Details on how to calculate mass is found below.
How to calculate mass?The mass of a substance in a solution can be calculated using the following formula:
Density = mass ÷ volume
According to this question, 5.5L of a HNO3 solution is given.
Density of HNO3 is 1.51 g/cm³
Volume of HNO3 = 5500mL
1.51 = mass/5500
mass = 8305g

Automobile catalytic Converters use a platinum callus to reduce air pollution by changing emissions such as carbon monoxide CO2 to carbon dioxide CO2 the uncatalyzed reaction is represented by the balance inflation below 2 CO + 02 2CO2 + heat determine the number of moles of O2 reaction with 28 moles of CO during this reaction
Answer:
14 mol O₂
Explanation:
The reaction between CO and O₂ is the following:
CO + O₂ → CO₂
We balance the equation with a coefficient 2 in CO and CO₂ to obtain the same number of O atoms:
2CO + O₂ → 2CO₂
As we can see from the balanced equation, 1 mol of O₂ is required to react with 2 moles of CO. Thus, the conversion factor is 1 mol of O₂/2 mol CO. We multiply the moles of CO by the conversion factor to calculate the moles of O₂ that are required:
28 mol CO x 1 mol of O₂/2 mol CO = 14 mol O₂

Write a summary on how to use a light microscope
DUE TODAY PLEASE HELP.
Answer:
Step 1: Connect the light microscope to a power source. If your microscope uses a mirror instead of an illuminator, you can skip this step. Instead, find a place where natural light is easily accessible
Step 2: Turn the revolving nosepiece so the lowest objective lens is in position.
Step 3: Mount your specimen onto the stage. But before doing so, see to it that your specimen is adequately protected by placing a coverslip on top of it.
Step 4: Use the metal clips to keep your slide in place. Make sure the specimen is positioned in the center, right under the lowest objective lens.
Step 5: Look into the eyepiece and slowly rotate the coarse adjustment knob to bring your specimen to focus. See to it that the slide does not touch the lens.
Step 6: Adjust the condenser for the maximum amount of light. Since you're on the low power objective, you may have to decrease the illumination. Use the diaphragm under the stage to adjust.
Step 7: Now slowly rotate the fine adjustment knob until you obtain a clearer image of your specimen.
Step 8: Examine your specimen.
Step 9: After you're done viewing with the lowest power objective, switch to the medium power objective and re-adjust the focus with the fine adjustment knob.
Step 10: Proceed to the high power objective once you have it focused.
